53.—(1) Each return delivered under article 52(1) shall be accompanied by a declaration made by the election agent in form CX set out in English and Welsh in Schedule 10.
(2) At the same time as the election agent delivers that return, or within seven days thereafter each constituency or individual candidate shall deliver to the appropriate returning officer a declaration made by him in the form CX set out in English and Welsh in that Schedule.
(3) Where a candidate is out of the United Kingdom when the return is so delivered—
(a)the declaration required by paragraph (2) may be made by him within 14 days after his return to the United Kingdom; and
(b)in that case, the declaration shall be forthwith delivered to the appropriate returning officer,
but the delay authorised by this provision in making the declaration shall not exonerate the election agent from complying with the provisions of this Order relating to the return and declaration as to election expenses.
(4) Where a constituency candidate or an individual candidate is his own election agent, the declaration by the election agent as to the election expenses need not be made and the declaration by the candidate as to election expenses shall be modified as specified in the form CX set out in English and Welsh in Schedule 10.
(5) If a candidate or election agent knowingly makes the declaration required by this article falsely, he shall be guilty of a corrupt practice.
